Henri Le Tonnelier de Breteuil (1848-1916) was a French aristocrat and politician.
Henri Le Tonnelier de Breteuil was born in 1848.[1] He was the son of Alexandre Le Tonnelier, Marquis de Breteuil (son of Achille Le Tonnelier de Breteuil), and his wife Charlotte-Amélie Fould, daughter of the financier Achille Fould.
Breteuil served as a member of the Chamber of Deputies, representing Hautes-Pyrénées.[1] He was a key negotiator in the Triple Entente.[1]
Breteuil resided at the Château de Breteuil.[2] He often invited his friend Marcel Proust, who based the character of Hannibal de Bréauté in In Search of Lost Time on him.[2] Breteuil commissioned architect Ernest Sanson to design his Hôtel de Breteuil in the 16th arrondissement of Paris, completed in 1892.[3]
On 3 March 1891, he married the American heiress Marcelite "Lita" Garner,[4] whose sister Florence Garner married the Scottish socialite Sir William Gordon-Cumming.
Breteuil died in Paris in 1916.[1]
